@Ar9Jim A simple, quick-to-market sonic holography component would have my vote. One function: updated sonic holography. In this case, less is more. None of us are getting any younger, and it seems to me having something to market quickly would make a lot of sense all around.
I echo what @jvandyke_texassaid about the circuit itself: it shoulld to be different, or upgraded. Otherwise, it would essentially be a new C-9.
And if it includes the Gundry circuit, it would definitely need to be switchable. It's been my experience when switching my Gundry circuit in and out that Gundry can negatively affect the sound of some recordings in terms of their holographic dispersion.
Thank you for this excellent news and informative update.
